Filed: 1997-07-30
Granted: 2002-08-20
Abstract: FIELD: chemical technology. SUBSTANCE: invention relates to a method of regeneration of high-fluorinated carboxylic acids from flows of exhausting gases. Exhausting gas is contacted with potassium carbonate-containing alkaline washing out solution with density above 1.15 g/cm 3  and separation of high-fluorinated carboxylic acid salt as a separate phase since in taken concentration perfluorocarboxylic acid potassium salt is insoluble in potassium carbonate solution followed by preparing high-fluorinated carboxylic acid from its. The preferable density value of washing solution is 1.2-1.4 g/cm 3 . Method provides the isolation of pure high-fluorinated carboxylic acids without loss and deposit formation in the prolonged exploitation of washing column.
